We are learning about different time zones around the world and how to calculate time differences.
Today I learnt how to calculate the time zones around the world. This was great because now I know more time zones around the world. The time zones are based on greenwich-mean-time (GMT) makes all the different time zones. If the country is on the left of Engalnd (where GMT originated From) the time is behind and if it is to the right the time is forward from GMT time. New Zealand is on the right of GMT so we are in the 'Future' compared to England. Not all countries have only one time zone, some have many time zones like Australia. A clear explanation of the theory we have learnt today. You could also have given an example of how far behind NZ another country is.

We are learning about exchange rates for currency.
Exchange rates change one form of currency to another. These help people to get the right amount of money where the currency is different. An example is 0.5699 Euro is the exchange rate. If someone had $800 N.Z money and wanted to change that into Euro, they would have 394.8 Euro. A good example.

We are learning about the difference between Celsius and Fahrenheit for temperature.
There are two measurements of temperature because earlier people used Fahrenheit for temperature and Fahrenheit was part of the Imperial System. Celsius, the more modern temperature, used mostly around the world. Fahrenheit is more likely to be used in America because the still use the Imperial System. The formula for the convertion from Fahrenheit to Celsius is C=(F-32)X5/9. A clear explanation Liam.

We are learning to use algebraic thinking to slove decimal subtraction problem.
The strategy that we learnt was to add or subtract the same from both numbers. For 19.42 - 5.87 you would add 0.13 to both numbers to make it 19.55 - 6 = 13.55. I found this strategy easier than most strategies. This has helped me because now I know an easier strategy for subtracting decimals.
I am pleased you found this helpful. It is definately an easy way to subtract decimals and can be done simply in your head. TC

We are learning to use temperature as a strategy to help us add and subtract integers.
Using temperature as a strategy is fun and easy because you can make up funny stories to help you solve + and - problems. Eg. +6 - -8 = +14. I find this strategy easy to use and I will remember it for when i need to add and subtract integers Liam I am really pleased you enjoyed this learning this strategy and that you find it a good way to solve integer problems.

We are learning to draw a histogram. Decide which kind of data that a histogram shows.
A histogram is the only bar graph thats is joined at every bit of data. Historgrams are are also the only bar graph that can show time series data. Historgrams always have the continuous data on the x axis and the discreet data always goes on they axis.Now I know how to use a histogram and the way it is supposerd to go. Since I had learnt what a histogram was I could add some thing to my "What I Know" list.

Today I learnt how to conduct a survey and make it into a box and whisker plot. Playing the games on digistore helped my knowledge of surveys and boxplots.Now I can conduct a survey/questionnaire for my statistical investigation this year. I also know how to write reccomendations and how to find implications in my solution. Knowing how to do a survey will help me further my knowledge in basic maths. Do you find this a useful resource? I think it is a great way of consolidating knowledge. Digistore is a useful resource because it has heaps of fun maths games that teach you all about different math topics in detail. 05.05.10
Today learnt how to draw a box and whisker plot and how to find ,lower, upper and inter quartiles. I also learnt to organise the data collected in numerical order. Then you count how many numbers there are and then find the median. then with the median find the middle number from the median to the left then to the right. With the quartiles and the median you draw the box. then place the highest and lowest numbers where they should go on the number line. Are you confident in interpreting these too? Yes I am confident in interopreting Box and Whisker plots. 12.05.10
Today I learnt the proper way to do a mathematical design. It is really fun being able to play around on publisher for maths. Doing the mathematical design has helped me with my knowledge of how to design something with one shape, I never knew playing with shapes is weird. I had trouble doing my questionnaire because i had trouble thinking of the qeustions to write. My hypothesis was easy because i knewe what to write and I just wrote what I thought.

WALT use excel to display data.
Today I saw how I did in the olympiad and I made two bad mistakes. but I learn from my mistakes. I found the Olympiad hard because i had trouble working out the answer. Also I learnt about how to create graphs on 07 excel and how to make chart titles and the y and x axis. Making a pie chart on excel is easy. I need to learn and know how to make a pie chart that is not computer generated. Did you miss that activity? See me and I will go through this with you. On Excel try to ensure your key is really clear and that anyone looking at it would understand what your graph is about.
